If we look at the dugong meaning: it is a marine mammal and the only sirenian present in this range. This mammal has a fusiform body with no hind limbs and dorsal fins but has paddle-like forelimbs. The fluked dolphin-like tail of dugongs makes them easily distinguish between manatees. Dugong also has unique teeth and skulls. Their teeth are simple and peg-like, unlike the elaborate dentition of the manatees. The snout of this mammal has adapted to be down so that it can easily feed in seagrass communities. Dugongs have been hunted on a large scale due to their meat and oil. Traditional hunting of this mammal still has cultural significance in various countries, including Pacific Islands and Northern Australia. Most of the population of this mammal is considered to be extinct due to this hunting.
